Answer 1

7.92%

Explanation:

Given the following

Weight of package at home = 20.2 ounces.

Decrement = 20.2 - 18.6

percentage error = decrement/wt at home * 100

percentage error = 1.6/20.2* 100

percentage error = 160/20.2

percentage error = 7.92

HEnce the percent error in the weight of the package is 7.92%
